Upgraded to get 800 out for a zoom meeting, how do I generate an 800 meeting number?

I just upgraded to a Pro account. I initially sent an email out with a free account. I didn't know you needed a Pro account in Zoom for the 800 number. I upgraded and there isn't a place I can find to resend or the process on how to generate an 800 number for my meeting, does anyone know how to do that please? Thanks!
